The defective of above-mentioned termination is: the contact area of O RunddichtringO and battery post is less, so that O-ring seals is not ideal to the sealing effectiveness of battery post, the electrolyte of storage battery still can enter in housing between O-ring seals, battery post, electric conductor is produced electrochemical corrosion, shorten the useful life of electric conductor.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of sealing property improved fast coupling line device for corrosion-resistant accumulator cell preferably.

for solving the problems of the technologies described above, the utility model provides a kind of improved fast coupling line device for corrosion-resistant accumulator cell, its structure is: the two ends of wire are respectively equipped with conducting ring and electric conductor, be provided with hollow horizontal round platform in the housing bottom opening, horizontal round platform is provided with cannelure, the bottom land cross sectional shape of cannelure is circular arc, the notch of cannelure communicates with the endoporus of horizontal round platform, the notch of cannelure also extends on the downside of horizontal round platform and described notch is the logical diffusion type of up and down continuous phase, the central angle of cannelure bottom land is 90-180 degree, O-ring seals is housed in cannelure, circle body less than this circle 1/3 volume in the O RunddichtringO is in cannelure, stretch into respectively in the endoporus of horizontal round platform also exposed under the downside of horizontal round platform greater than the circle body of this circle 2/3 volume in the O RunddichtringO, wire penetrates the housing inner chamber and closely cooperates with housing, electric conductor and fixture are placed in housing relative to one another, electric conductor top and wire are affixed, the electric conductor bottom is half cylinder coincideing with the battery post shaped upper part watt, fixture is the smaller part cylinder that coincide with the battery post shaped upper part watt, the screw terminal of fastening bolt is in the horizontal precession housing of the lower sidewall of housing.

For the purpose of the concise description problem, below to improved fast coupling line device for corrosion-resistant accumulator cell described in the utility model all referred to as this termination.

After adopting above technical scheme, the circle body greater than this circle 2/3 volume in the O RunddichtringO is exposed outside cannelure.

Case cover is covered on battery post (being about to battery post upwards pushes in housing), and the turn fastening bolt is held battery post top tightly electric conductor and fixture jointly, and the installation of this termination can be completed.at this moment, circle body less than this circle 1/3 volume in O-ring seals is squeezed in cannelure, be squeezed in gap between battery post and horizontal round platform endoporus hole wall greater than the circle body of this circle 2/3 volume in the O RunddichtringO, making the battery post bottom is O-ring seals institute banding, be the sealing contact condition between battery post and housing, wire and housing closely cooperate in addition, the lower sidewall thread connection of fastening bolt and housing, therefore, electric-conductor is subject to the tight protection of housing and is isolated from the outside, the excessive electrolyte of storage battery can't be from the bottom opening of housing, the screw-on place of the connection place of wire and housing and fastening bolt and housing enters in housing, therefore can guarantee that electric conductor can not come in contact with electrolyte, effectively avoid electrolyte to carry out electrochemical corrosion to electric conductor, make the electric conductivity of electric conductor strong, useful life is longer.In sum, the contact area of O RunddichtringO and battery post is larger, so that O-ring seals can produce good sealing effectiveness to battery post, the electrolyte of storage battery can not enter in housing between O-ring seals, battery post, can not produce electrochemical corrosion to electric conductor, extend the useful life of electric conductor.Therefore, the sealing property of this termination is better.

The central angle of described cannelure bottom land is 172 degree.
